Wastewater treatments

STANDARDS FROM OUR PARTNER

In order to address the different wastewater treatment problems that might be: deoiling, skimming, recovery of supernatants, pumping, separation of coalescent oils, filtration, or physico-chemical treatment, SORIM HOLDING proposes a wide range of standard products suitable for water treatment.

This standard equipment, which has been built and proven for many years, continues to attest to the reliability offered by its simple and sturdy construction.

Analysis of the correct choice of materials and equipment for each configuration allows the optimum system size to be chosen in terms of quality, performance and reliability.

WASTEWATER TREATMENT PROCESSES

In order to be able to address turnkey solutions and to offer a performance guarantee on our installations, we carry out auditing, and on-site or laboratory testing in order to determine the best technical solutions to put into operation.

SORIM HOLDING addresses all turnkey situations for wastewater treatment with the following technology:

Physico-chemical treatment

• Neutralisation
• Coagulation /Flocculation
• Liquid-solid separation
• Settling

Electrocoagulation treatment

• Our partners designed electrocoagulator provides manufacturers with a compact, effective and easy to use system. The scraping system between the anode and the cathode prevents clogging and enables continuous treatment. The electrocoagulator is particularly effective in eliminating particulate COD, Suspended Solids, hydrocarbons and heavy metals.

Thermic treatment

• Vacuum evaportation
• Recycling, zero discharge

Traitement par Ozonation Catalytique

• Problem COD hardness
• The combination of our partners expertise and its experience in incorporating complementary technology is a guarantee for your turnkey solution.

SKIMMING / DEOILING

Our self-adjusting skimmers combined with a volumetric pumping unit and our unique designed deoiler (completely static with no consumables) allow two liquids of different densities to be separated by density difference. The applications are numerous: API, degreasing bath maintenance by deoiling, deoiling before further treatment.

OLEOFILTRATION –   COALESCER FILTER SEPARATOR
The Oleofilter is a vertical filter with a homogeneous oleophilic ceramic layer (media manufactured by our partner). This filtration media enables retention of all traces of hydrocarbons that are nonsoluble or not stabilized by a chemical agent. The Coalescer Filter Separator combines an initial deoiling stage with filtration on oleophilic ceramic.

Oleofiltration has the following advantages:

• Elimination of all traces of hydrocarbons that are not solubilised or chemically stabilized (< 10 ppm)
• No addition of coagulant or flocculant required
• Filtration of the entire flow to be treated
• Combines the performance of a sand filter and a powerful coalescer
• Regenerates by backflush in order to recover its initial efficiency

ELECTROCOAGULATION
The unique designed electrocoagulator of our partner provides manufacturers with a compact, effective and easy to use system. The scraping system between the anode and the cathode prevents clogging and enables continuous treatment. The electrocoagulator is particularly effective in eliminating particulate COD, Suspended Solids, hydrocarbons and heavy metals.

PHISICO-CHEMICAL PROCESS
SORIM HOLDING is able to determine the appropriate size of a Physico-chemical water treatment station with the different stages that are necessary (coagulation, neutralization, flocculation, and settling). Our partner incorporates into its treatment lines its breveted lamellar settler, which offers the customer not only increased performance but is also extremely compact. These discharge water stations enable elimination of particulate COD, Suspended Solids and heavy metals.

LAMELLAR SETTLING

Our partners unique designed lamellar settler with self-adjusting floating roof is an extremely compact system for liquid/solid separation via sedimentation by vertical drainage. It consists of multiplying, in the same unit, the water-sludge separation surfaces and enables separation of primary, biological or physico-chemical sludge.

VACUUM EVAPORATION
The vacuum evaporator with Mechanical Vapour Compression allows the manufacturer either to recycle his effluent or to evacuate it into a wastewater treatment plant or into the environment. This technology reduces power consumption and provides manufacturers with a pertinent solution for treatment of oil emulsions or in the field of surface treatment.

CATALYTIC OZONATION
The catalytic ozonation developed by our partner via its own specialised subsidiary enables treatment of hard COD, refractory to conventional treatment. The catalyst enables better purification yields to be obtained and considerable reduction in the quantity of ozone to be added. This technology is also suitable for use between two stages of a biological treatment in order to increase the effluent biodegradability.
